What number goes into 5 7 and 9?
5 and 7 are prime numbers. and 3 goes into 9, so the only number that goes into 5, 7, and 9 is 1. They are what we call "relatively prime", even though 9 is not prime, because they have no common factors other than 1.
What is the smallest number divisible by 5 and 9?
45/5 = 9 45/9 = 5 Therefore, the smallest number divisible by both numbers is 45.
Five less than a number is equal to 13 decreased by the number?
The number = 9Working:n - 5 = 13 - n(+ 5 on both sides)n = 18 - n(+ n on both sides)n + n = 18= 2n = 18(divide both sides by 2)n = 9So...9 - 5 = 13 - 9(9 - 5 = 4)(13 - 9 = 4)
Divide a number by 5 and add 4 to the result the answer is 9?
Let's represent the number as x. The equation can be written as (x / 5) + 4 = 9. To solve for x, we first subtract 4 from both sides to isolate the fraction: (x / 5) = 5. Next, we multiply both sides by 5 to cancel out the division: x = 25. Therefore, the number is 25.
What number goes into 225?
Each of these numbers goes evenly into 225: 1, 3, 5, 9, 15, 25, 45, 75, 225
